Abstract
BackgroundPeriprosthetic joint infection (PJI) is a rare but devastating complication after total joint arthroplasty. There is a paucity of data on the incidence and prevalence of periprosthetic infection in mainland China. This study aimed to analyze the rates of surgical revision after arthroplasty due to PJI and the procedures followed in Beijing, China.MethodsThe study involved a retrospective multicenter cross-sectional survey of patients undergoing revisions for periprosthetic infection after hip/knee arthroplasty at nine hospitals in Beijing from 2014 to 2016. Age, gender, body mass index, primary diagnosis, comorbidity, primary surgery, treatment methods, and post-revision complications were analyzed.ResultsA total of 38,319 hip/knee arthroplasties and 366 (0.96%) revisions for PJI were identified. Of these, 161 (161/14,110; 1.14%) revisions involved hip arthroplasty, whereas 205 (205/24,209; 0.85%) revisions were due to knee arthroplasty. Procedures for revisions of infected hip included 7 (4.3%) cases of open debridement and prosthesis retention, 32 (19.9%) cases of one-stage exchange, 121 (75.2%) cases of two-stage exchange, and 1 (0.007%) case of hip dissection. As for the infected knee, the procedures included 45 (22.0%) cases of open debridement and prosthesis retention, 13 (6.3%) cases of one-stage exchange, 143 (69.8%) cases of two-stage exchange, and 4 (0.02%) cases of knee fusion.ConclusionsThe study found the rates of revision due to PJI to be low. Nonetheless, the incidence of PJI in mainland China could be higher and calls for more elaborate studies in geographically and socioeconomically diverse health institutions.

Patients Clinical data of patients diagnosed with PJI following hip/knee arthroplasty were collected retrospectively for the time period between 1 January 2014 and 31 December 2016 in the nine health institutions that serve as main arthroplasty centers in Beijing, China
Knee replacement surgery Our study identified 24,209 cases of either total or partial knee arthroplasty (Table 1)
Summary
Periprosthetic joint infection (PJI) is a rare but devastating complication after total joint arthroplasty. This study aimed to analyze the rates of surgical revision after arthroplasty due to PJI and the procedures followed in Beijing, China. Periprosthetic joint infection (PJI) is a potentially devastating complication after joint replacement. This condition is associated with pain, compromised joint function, prolonged hospitalization, and increased cost of medical care. Treatment options for periprosthetic infection include debridement, use of antimicrobials, and surgical revision with the aim to restore joint function and relieve pain [4,5,6]. Surgical revisions and other treatments for PJI are expensive. In the USA alone, the estimated cost of treating
